A year later, Microsoft finally launched the long-awaited fourth generation surface product, Surface Pro4, with a new configuration, powered by Intel's sixth generation Core Skylake processor, which has more powerful performance and a thinner appearance, and was popular with users on the day of its launch. Microsoft launched the Surface series in 2012, which is positioned as a "tablet". However, its first and second generations are very popular. Although they have more powerful hardware, it is difficult to associate this tablet with its overweight and thick body. Although the external Type Cover keyboard can be extended to a laptop, it has only 10.6-inch screen and is difficult to provide users with a good operating experience.
The appearance of Surface Pro 3 has changed this situation. It is lighter and thinner, but has a 12 inch screen. It can be used as a "deformation book" completely. In addition to the larger screen, its configuration is almost at the same level as the Ultrabook, which can fully meet the daily use needs. The positioning of Surface has gradually evolved from "tablet" to "next-generation PC". Surface is not only a tablet, a notebook, a computer, but also Microsoft's vision for the future.
Let's take a look at the configuration of Surface Pro 4:
12.3-inch PixelSense 2736 × 1824 (267 PPI) IPS LCD
From Intel Skylake architecture Core M3 processor (4M cache, 2.20 GHz), up to Intel Core i7 processor (8M cache, 3.80 GHz) can be equipped
4 GB/8 GB/16 GB DDR3L 1600 MHz memory
Solid state disk with PCIe interface 128 GB/256 GB/512 GB/1 TB
8 megapixel rear camera, supporting 1080p recording, 5 megapixel front camera
USB 3.0 port, Micro SD slot, Mini DisplayPort, SurfaceConnect charging port
Support 802.11a/b/g/n/ac dual band Wi Fi, Bluetooth 4.0
Let's first take a look at the structure of the Surface Pro4 through X-ray. With the continuous progress of technology, our disassembly can also be more convenient. Through X-ray analysis, we can roughly understand the internal structure of the fuselage, which is convenient for us to disassemble.
Let's take a look at the camera first. Unlike previous generations, this model seems to be equipped with a camera module with three openings. Next to it is a microphone.
The design of the shell is clear, and the combination of camera, microphone and indicator light.
Let's take an X-ray to see the structure of the camera module. It seems that there are two cameras, and the purpose of the components beside them is not clear.
The hinge shaft on the back is of exposed design, and Microsoft has applied lubricating oil on the hinge. Although it meets the lubrication requirements, it also determines that it is easy to stick dust, hair or thread ends. Users need to pay attention to it in use.
Microsoft is very careful in the design of this hinge, and the internal structure is complex through our X-ray inspection.
Like Sophie in the past, we begin to disassemble the screen by heating it to soften the glue under the screen.
Slowly pull up the display with the suction cup.
Use a paddle to pry up slowly along the edge of the screen and the body.
There are two flat cables at the bottom of the screen. We should pay attention to them.
Unplug the flat cable with a crowbar.
Detach the screen.
There is a small circuit board at the bottom of the back of the screen.
Let's see what chips are on the circuit.
Let's look inside the fuselage. There are no parts in the red circle. We speculate that this location should be the location of the fan and radiator of Sophie's hybrid refrigeration system, but since we disassembled the Core m3 processor version with only 4.5 watts of power, the heat output is low, so no fan is installed.
Remove all the metal shielding covers and ribbon cables on the mainboard.
The motherboard is very compact in design, and most of the components are tightly assembled. First, we remove the SSD and unscrew the screws to remove it.
The hard disk of Sophie 4 is a PCIE interface SSD provided by Samsung, and the model is PM951.
Let's see what chips are on this SSD.
Red: Samsung S4LN058A01 CIE 3.0 x4 NVMe flash memory controller
Orange: Samsung K9CHGY8S5C 64 GB NAND flash memory
Yellow: Samsung SEC 525 K4E4E32
Green: Texas Instruments TPS22966 5.5V, 6A, 16m Ω, dual channel load switch
Sophie 4's cooling module is very impressive, with a long heat pipe and a large area of pure copper heat pipe.
This is a hybrid cooling system, which combines active cooling and passive cooling. Passive cooling is used when the temperature is low, and active cooling fan is started when the temperature is higher.
Unscrew the screws to remove the camera module attachment plate.
Let's take a look at this mysterious camera module
Use a crowbar to unplug the camera cables one by one.
From left to right are: front 5 megapixel camera, infrared facial recognition camera (supporting Windows Hello), rear 8 megapixel camera.
After unplugging the flat cable and cable, we can remove the two speakers in the two corners.
The power key and volume key are integrated on one of the speakers. Although this design can make the internal structure more simple, if damaged, the speaker will be replaced together, increasing the maintenance cost.
Finally, the motherboard can be removed. Be careful not to damage the side connector when removing the motherboard.
Let's take a look at the chips on the motherboard.
Red: Intel SR2EN Core M3-6Y30 processor (4M cache, maximum frequency 2.20 GHz)
Orange: Samsung K4E8E304EE-EGCF 8Gbit LPDDR3 memory (4 pieces × 1 GB, 4 GB in total)
Yellow: Marvell Avastar 88W8897 802.11ac/NFC/Bluetooth SoC
Green: Freescale Kinetics KL17MKL17Z256VFM4 48MHz ARM Cortex-M0+
Light blue: ITE IT8528VG
Dark blue: Ruiyu ALC3269 audio encoder
Purple: Ruiyu RTS5J04 micro SD card reader controller
Red: Huabang 25Q128FV serial NOR flash memory
Orange: TI TPS51367 FET converter
Yellow: Infineon SLB96659TT20 trusted platform module
Green: Monolithic Power Systems MP3388S 50V, 8-String, Step Up, White LED driver
Look at the opposite.
The internal components of the fuselage are rarely disassembled. Now we start to disassemble the battery. First, heat the back cover to soften the glue.
Use the card to slowly separate the glue under the battery.
Sophie 4 is equipped with a 7.5V 38.2Whr battery with a capacity of 5087mAh, which is about 9% less than the previous generation of Sophie. Although the capacitance of the Sophie 4 has shrunk, the battery life of the Sophie 4 is likely to increase due to the use of a new generation of processors, motherboard chips and more energy-efficient screens.
Well, our disassembly will be completed here. The old rule requires a family photo. The iFixit gave the Surface Pro 4 2 points for maintenance (10 points for the easiest maintenance), which is a very low score and very difficult for maintenance. The internal design is very compact. Almost all the components are welded to the motherboard. Only the SSD can be replaced by itself, but the whole machine is bonded by a lot of glue, so it is difficult to disassemble by itself.
